TAKE-UP.

To all whom it may concern.

Bev it known that I, GARRET B. OsTER- HOUT, a citizen of the UnitedStates of America, and residing at Providence, in the county ofProvidence and State of Rhode Island, have invented a certain-new anduse 7 in the position shown in Fig. 1; and

Fig. a is a perspective of the take-up cam.

The two threads A and B here shown subjected ,tothe action of thetake-up may be regarded as the threads of the two loopers I71, and 70 ofthe patent-above mentioned, although the present device is obviouslyadaptable to other machines. The threads pass through independent guideeyes in the rod 10 to the tension devices 11.12, thence to the guideeyes in the rod 13 and past the take-up devices to the guide eyes in rod14. whence'they are led to the loopers or other part, as may be, in theparticular machine in which the invention is embodied.

The take-up as shown, comprises a rotary element lying between thethreads A and B and. adjustably-mounted by means of a set screw 15 onthe shaft 16 journaled at one end in a frame element 17. While thetake-up element may be solid, it is preferable for the sake oflightness, to form it with a body web 18- substantially alined with thethreads in their normal course between guides 13 and 14. This web isperforated to receive the shaft 16 and is provided on its opposite faceswith peripheral cam flanges or skirts 19 and 20. For the particularmachine in question it is desirable that the take-up should operatedifferently upon the diflerent threads and the cams are shapedaccordingly, although they may be of any suitable shape to meet theparticular needs Specification of LettersPatent.

of the machine in which the take up is installed. As here shown each cam19 and 20 merges into the web member 18 at the points 21 substantiallyopposite each other on each face of the web 18. r

The thread A coming from tension device 11 passes through one of theguide eyes in'rod 18, thence over shaft 16 and on one side of thetake-up to a guide eye in rod 14. Thread 13 passes through the otherguide eye in rod 13, thence over shaft 16 on the opposite side of thetake-up to the other guide eye in rod 14. When the take-up. isin theposition shown in Fig. 1 and the threads A and B lie against the web 18atthe points 21 at which the cams 19 and 20 mergeinto the web, thethreads pass in their normal course substantially directly between vrods13 and 1 1. As the shaft 16rotates however,

the take-up cams spread the threads inop-v posite directions andtheslack therein is taken up in accordance with the shape of the cams. Anytendency of the threads to ride up on the periphery of the web 18 isprevented not only by thetension devices which keep the thread taut, butalso by the arrangement of the guide rods closely adja cent the take-up.The threads are merely displaced axially of the take-up in oppositedirections along the shaft 16 by the. action of the cams. I

The formation of the slack by the peculiar movements of the loopers orother executive parts and the cooperation of the take-up therewith istoo well understood to need further explanation or illustration. Asabove stated, the cams of the take-up may be of any suitable shape, andI do not limit my invention to the precise forms shown.

I claim as my invention r Patented Oct. 2,1917.

Application filed November 12, 1914. Serial No. 871,749. r

1. A two, thread take-up comprising a rotary member with cam surfacesarranged to enter between a pair of threads and displace the same inopposite directions, for

the purpose described@ 7 2. A two thread take-upcomprising a rotarymember having cams on its opposite faces arranged to enter between apair of threads and displace the same in opposite directions. 7

3. A two thread take-up'comprising a lo tary member having means on itsopposite faces adapted to enter between a pair of threads and displacethe same in opposite axial directions, for the purpose described.

4:. A two thread take-up comprising a retary disk having peripheral camson its opposite faces adapted to enter between a pair of threads anddisplace the same in opposite axial directions, for the purposedescribed.

5. In mechanism of the type described, guide means for spacing apart apair of looper threads and rotary means intermittently spacing saidthreads abnormally apart to afford a take-up.

6. In mechanism of the type described, a guide arm having a pair ofguide eyes for spacing apart a pair of looper threads and rotary meansadjacent said guide arm'for intermittently spacing said threadsabnormally apart to afford a take-up.

7. In mechanism of the type described two guide arms each having a pairof guide eyes for spacing apart a pair of looper threads and rotarymeans arranged between the said guide arms for intermittently spacingsaid threads abnormally apart to afford a take-up.

8. A two-thread take-up comprising a rotary member having at each endthereof cam surfaces on opposite sides of its axis of retation, for thepurpose described.

9. A. two-thread take-up comprising a retary member having at each endthereof cam surfaces on opposite sides of its axis of retation, the camsurfaces on one end being unlike those at the other end to impart adifferent take-up action to the thread engaged thereby.

10. A two-thread take-up comprising a rotary member having at itsopposite ends cam surfaces shaped to impart two inclependent take-upactions on a single revolution to the threads engaged thereby.

11. A two-thread take-up comprising a rotary member having at itsopposite ends cam surfaces shaped to impart two inde pendent take-upactions on a single revolution to the threads engaged thereby, each camat a given end of the rotary member being of like efl ective shape toimpart two like take-up actions on a single revolution of said member. V

12. A two-thread take-up comprising a rotary member having at itsopposite ends cam surfaces shaped to impart two inde pendent take-upactions on a single revolution to the threads engaged thereby, thetake-up cams at one end being of different elfective shape from those atthe other end of the rotary member to impart a different take-up action.

18. A two-thread take-up comprising a rotary member having at itsopposite ends cam surfaces shaped to impart two independent takeupactions on a single revolution to the threads engaged thereby, thetake-up cams at one end being of difi'erent eflective shape from thoseat the other end of the rotarv member to impart a different.

take-up action. while the cams at a given end of said member are of likeeffective shape to impart two like take-up actions on a singlerevolution of said member.

14. In a mechanism of the type described affording a take-up action fora pair of looper threads, a rotary take-up member engaged between saidthreads and having cam surfaces serving to take-up the slack in thethreads during the operation of the mechanism.

15. In a mechanism of the type described afiording a take-up action fora pair of looper threads, a rotary take-up member enbetween said threadsand having cam surfaces of dissimilar shape serving to takeup theunequal slack in said threads during. the operation of the mechamsm.

In testimony whereof I have signed my name to this speeificatlon, 1n thepresence of two subscriblng witnesses.
